Canterbury Police have executed four search warrants as part of the investigation into the collapse of the CTV building.
Detective Superintendent Peter Read says the warrants form part of the ongoing investigation. Documents and items of interest have been seized.
In September 2014 New Zealand Police announced that it would be advancing a criminal investigation after assessing a large amount of information regarding the collapse of the CTV building during the February 2011 earthquake.
Police have also engaged the services of engineering consultants Beca to provide expert opinion to the investigation.
Detective Superintendent Read says the investigation involves consideration of a large amount of complex, technical information to inform police on recommendations about any criminal liability.
Any decisions will be subject to legal review before the final outcome of the investigation is known, which will not be until later this year.
